1) Let, the original price = x
We know, sale price is 100 - 15 = 85% of original price.
So, x * 85% = 59
x * 0.85 = 59
x = 59/0.85
x = 69.41
In short, Your Answer would be Option B
2) Let, the original price = x
We know, sale price is 100 - 30 = 70% of original price.
x * 70% = 79
x * 0.70 = 79
x = 79/0.70
x = 112.85
In short, Your Answer would be $112.85
Hope this helps!
